INVALID-CHAIR.

SPECIFICATION forming part of Letters Patent No. 438,945, dated October 21, 1890. Application filed June 23, 1890. Serial No. 356,468. (No model.)

To all whom it may concern.-

Be it known that I, NICHOLAS PETRY, a citizen of the United States, residing at Rockport, in the county of Atchison and State of Missouri, have invented a new and useful Invalid-Chair, of which the following is aspecification.

This invention relates to chairs, and more particularly to that class thereof known as invalidchairs;and the object of the invention is to effect improvements over devices of this same general character heretofore exist- Ing.

To this end the invention consists in the specific details of construction hereinafter more fully described, and illustrated in the drawings, in which Figure 1 is a front elevation of this improved chair in its normal position. Fig. 2 is a side elevation of the same with the foot-rest distended. Fig. 3 is a section on the line?) 3 of Fig. 1, showing the back of the chair as thrown partly back and the foot-rest in a partly-distended position. Fig. 4 is a bottom plan view of one of the arms. Fig. 5 is a perspective detail of the foot-rest removed. Fig. 6 is a transverse section.

Referring to the said drawings, the four legs L support the seat S, and the back B is hinged at b to this seat, as shown.

A are the arms, which are pivoted at their front ends to uprights a from the seat, and these arms are made hollow, as best seen in Fig. 4.

R are rack or ratchet bars, pivoted, as at r, to the back and extending into the hollow arms A, and P are spring-catches inserted into the sides of the arms A, and Whose tips engage the teeth in said bars R, whereby the back can be adjusted at any desired angle to the seat. In the said seat is formed a hole near each edge of the chair, into which extends a rack or ratchet bar R, the same as the bar above described, and a catch Pnear each edge ofthe seat engages the teeth in this bar in the same manner.

F is a foot-rest standing normally against the front of the bodyD of the chair, as shown in Fig. 1, and to the upper corners of this foot-rest the front ends of the bars R, just described, are pivotally connected. Curved ratchet-bars O are pivoted to the sides of the foot-piece near its lower end and extend I loosely through eyes I, formed in the front wall of the body D, as shown. By this construction the upper edge of the foot-piece can be drawn outwardly to any desired position and there locked by the catches P, and the lower edge can be drawn outwardly and be locked by engaging the ratchet-teeth of the curved bars 0 with said eyes I in a manner which will be readily understood.

When it is desired to return the foot-rest to its normal position, the curved bars are lifted so that their teeth disengage the eyes, the catches P are drawn slightly outward, and the foot-rest is pushed backwardly to the position shown in Fig. 1.

The body D is hollow, and within the same is a box X, having a hinged door 01 at the rear. In this box can be placed a vessel that may be pushed forward beneath a hole 0 in the seat,.and the upholstered seatU may be raised when it is desired to use the chair as a commode.

What I claim is- In an invalid-chair, the combination, with the seat having a hole extending longitudinally therethrough along each side and eyes at the front of the body, of a footrest, rackbars pivoted to its upper corners and sliding loosely in said holes, spring-catches inserted in the seat near its edges and engaging the teeth of said rack-bars, and curved ratchetbars pivoted to the sides of said foot-rest and passing loosely through said eyes, substan-
